Microsoft aiming to regain marketshare from Firefox

Microsoft recently hold a secret webcast in which it discussed several potential fixes to Internet Explorer in order go regain market share it lost to other browsers - such as Firefox.

But because Microsoft has made the browser inextricably integrated with Windows, any upgrades will likely have to be delivered through a service pack update to the operating system, which is something Microsoft said probably won't happen. The company is looking at whether service packs might be viable, sources said.
